Over the last 15 years there has been a paradigm shift in North America from hydrocarbon production from conventional, permeable reservoirs to ultra-low permeability, unconventional reservoirs. The exploitation of unconventional resources is made possible by injection of large volumes (millions of litres) of fluid at high pressures to hydraulically create a permeable fracture network in the reservoir. The process of hydraulically fracturing in some areas result in anomalous induced seismicity (AIS), and the fluids used may damage the reservoir and are viewed by some as potential contaminants. The potential for AIS and real or perceived problems associated with the large volume of fluid utilised are the most important issues currently facing sustainable development of unconventional hydrocarbon resources. Our research will contribute to: 1) prevention and/or mitigation of AIS due to hydraulic fracturing; 2) understanding fluid rock interactions to minimize reservoir and fluid damage; and 3) better characterisation of reservoirs to optimise exploration and production.

过去 15 年里，北美油气生产发生了范式转变，从常规渗透性油藏转向超低渗透性非常规油藏。通过在高压下注入大量（数百万升）流体，以水力方式在储层中形成可渗透的裂缝网络，从而使非常规资源的开采成为可能。某些地区的水力压裂过程会导致异常诱发地震活动（AIS），所使用的液体可能会损坏储层，并被一些人视为潜在污染物。 AIS 的潜力以及与大量流体使用相关的实际或感知问题是当前非常规碳氢化合物资源可持续开发面临的最重要问题。我们的研究将有助于：1）预防和/或减轻水力压裂引起的AIS； 2）了解流体岩石相互作用，以尽量减少储层和流体损害； 3) 更好地描述储层，以优化勘探和生产。
